as i speak my dad is on a road trip to buy a ski boat that i will use for wakeboarding. the boat is a '95 ski centurion la pointe. i would like some suggestions of how to weight this thing. i have two 440# sacs. also my dad was thinking of putting a large fuel tank or similar and make our own built in ballast tank which be located right under the back seat. im also guessing i will need to weight the front a bit. anyone in the similar situation and how do you weight it?
